Multilevel security
You can improve the security of your Db2 applications when you add RACF security labels to Db2 objects or row-level security on a multilevel-secure system.
Multilevel security is a security policy that allows the classification of data and users based on a system of hierarchical security levels combined with a system of non-hierarchical security categories.
This document does not address the use of Db2 and the RACF access control module in a multilevel-secure environment.
